The advantage of this is that if you only need to use the SVG rendering mode, the bundle will not include the <code>CanvasRenderer</code> module, which is not needed.</p></blockquote> <p>The "Full Code" tab on our sample editor page provides a very convenient way to generate a tree-shakable code.

The advantage of this is that if you only need to use the SVG rendering mode, the bundle will not include the <code>CanvasRenderer</code> module, which is not needed.</p>\n</blockquote>\n<p>The "Full Code" tab on our sample editor page provides a very convenient way to generate a tree-shakable code.
